McBSP New Block Interrupt Does Not Occur for Start of Block 0

2.0
When end-of-block interrupt is selected ((R/X)INTM=01b), McBSP new block interrupt does
not occur at end of frame (i.e., before block 0). (Internal reference number 4357)
This interrupt is used when on-the-fly channel selection/enabling is being performed. A static
channel selection/enabling avoids this.
DMA/Internal Data Memory: First Load Data Corrupted When DMA in High Priority
2.0
In the case of a single load from A side or B side followed by two loads in parallel from both
sides, and in concert with a DMA high-priority access to the same bank as the parallel load,
the DMEMC provides corrupt data for that first load. (Internal Reference Number 3858)
Example:
LDW
.D1
LDW
.D2
|| LDW
.D1
Avoid high-priority DMA transfers to/from internal data memory during these conditions.
2.0
The following enhancements were made in 2.1.
When FRST transitions to a 1, the first frame sync is generated after 8 CLKG clocks. The 2.0
implementation was such that the first frame sync was generated after FPER+1 number of
CLKG clocks.
FRST = 1 is valid only when GRST = 1. In other words the user has to set FRST = 1 only after
GRST = 1. If not, write to FRST = 1 is ignored or rather a zero is forced on FRST by the logic.
During normal operation, when FRST = 1 and GRST = 1, and now the user puts the sample
rate generator in reset (GRST=0) without first clearing the FRST bit to zero, then the logic will
force a zero to the FRST bit before shutting down the sample-rate generator.
